The Oscars is the biggest night in Hollywood, when A listers take to the red carpet en masse for a evening of celebrating the year's best films.

Guillermo del Toro's The Shape of Water is leading the race with 13 nods. It follows the story of Elisa, a mute, isolated woman who works as a cleaning lady in a hidden, high-security government laboratory in 1962 Baltimore.

It is up for Best Picture alongside Darkest Hour, Dunkirk, The Post, Call Me by Your Name and last year's breakthrough horror Get Out.

Meryl Streep has been nominated for Lead Actress - for her role as the first female publisher of a major American newspaper - in The Post, alongside Margot Robbie for I, Tonya, Frances McDormand for Three Billboards Outside Ebbing, Missouri and Sally Hawkins for The Shape of Water.

Meanwhile, Brit Gary Oldman is up for Lead Actor, for his portrayal as Winston Churchill in Darkest Hour. Film experts are predicting that he will come home with the prize, given that the 59-year-old has already won a Golden Globe, a Critics' Choice Award and a Screen Actors Guild (SAG) for the role.
